    Young Children and Parents' Labor Supply during COVID-19
    ABSTRACT: We study the COVID-19 pandemic’s effects on the labor supply of parents with young children. Using the monthly Current Population Survey, and following a pre-analysis plan, we use three difference-in-differences variations to compare workers with childcare needs to those without. The first compares parents with young children and those without young children, while the second and third rely on the presence of someone who could provide childcare in the house: a teenager in the second and a grandparent in the third. We analyze three outcomes: whether parents were “at work” (not sick, on vacation, or otherwise away from his or her job); whether they were employed; and hours worked. Contrary to expectation, we find the labor supply of parents with young children was not negatively affected by the COVID-19 pandemic. Instead, some evidence suggests parents with young children were more likely to be working after the pandemic unfolded. Moreover, our results are not systematically different for men and women. This suggests that other factors like employer adjustments to allow employees to work at home and the availability of informal sources of childcare allowed parents to avoid major shocks to their labor supply during the pandemic.


    Physician Response to Prices of Other Physicians: Evidence from a Field Experiment
    • Contact me for early draft
    ABSTRACT: I examine the importance of cost information in the physician referral process. I partner with a group of physician medical practices -- an Independent Practice Association ("IPA'') -- to perform a field experiment testing whether providing information on the costliness of specialist physicians to primary care physicians (PCPs) alters the PCPs' referral behavior. The IPA's primary care practices were assigned randomly to treatment or control groups, and the treatment group practices were provided a list of average costs for several ophthalmologists that are affiliated with the IPA. Using data collected by the IPA, I compare differences in referral rates to the ophthalmologists of interest between the treatment and control groups. My results suggest that, during the first two months following the distribution of the cost list, the treatment group PCPs reallocated referrals towards the least expensive ophthalmology practice by 112% when the patients were the type where the costs incurred by the IPA for the referral depend on the treatment choices of the specialist. This large effect dissipated significantly, though not completely, over the following four months. For patients where specialist treatment choices have little impact on the costs the IPA incurs for referrals, I find no response to the treatment. This contrast in results suggests that PCP responses were influenced by cost reduction motives.

    Does Government Health Insurance Reduce Job Lock and Job Push?
    ABSTRACT: I study job lock and job push, twin phenomena believed to be partially due to employment-contingent health insurance (ECHI). Using variation in Medicaid eligibility among household members of male workers to identify changes in those workers’ reliance on ECHI, I estimate notable job lock and job push effects. For married male workers, a 15 percentage point increase in the likelihood a household member is eligible for Medicaid increases the rate of voluntary job exits over a four-month period by 14 percent. For job push, the same increase in a household member’s likelihood of Medicaid eligibility reduces the transition rate into jobs with ECHI among all male workers by 8 percent.


    In Sickness and in Health: Interaction Effects of State and Federal Health Insurance Coverage Mandates on Marriage of Young Adults
    ABSTRACT: We study the interaction of state and federal dependent health insurance mandates on young adult marriages. Using a new dataset on state-level mandates, we show marriage restrictions of these laws reduced marriage likelihoods by about two percentage points. When the Affordable Care Act (ACA) was enacted, its mandate ended marriage restrictions, encouraging marriage among those previously eligible for state mandates. However, among those ineligible for state mandates, it discouraged marrying to obtain insurance through spouses. The combination of these contrasting ACA effects eliminated the marriage gap. We also find these marriage effects resulted in corresponding impacts on out-of-wedlock births.


    A Reevaluation of the Effects of State and ACA Dependent Coverage Mandates on Health Insurance Coverage
    ABSTRACT: We study state and federal health insurance coverage mandates for young adults. Despite consistent findings that the Affordable Care Act's (ACA) federal mandate was effective, research has disagreed on whether pre-existing, state-level mandates were successful in increasing coverage. We reconsider the issue with a new analytical perspective and newly available, accurate data on state mandates. We show that the impact of the state mandates was substantive and concentrated among young adults between ages 19 and 23. Our estimates indicate that the dependent coverage rose by 3.9 percentage points and overall coverage rose by 3.3 percentage points. Crowd out of coverage through young adults' own jobs was negligible. For those above 23, we find little evidence of changes in coverage. We incorporate these insights into analysis of the ACA's mandate, showing its effects were focused among those who were not eligible for state mandates, or were eligible but older than 23. Our results suggest eligibility restrictions played important roles in limiting the scope of the state mandates, but they can be practical and effective tools for policymakers looking to ensure or expand coverage for young adults in the face of uncertainty about the ACA.


    The Effect of Health Insurance on Crime: Evidence from the Affordable Care Act Medicaid Expansion
    ABSTRACT: Little evidence exists on the effect of the Affordable Care Act (ACA) on criminal behavior, a gap in the literature that this paper seeks to address. Using a simple model, we argue we should anticipate a decrease in time devoted to criminal activities in response to the expansion, since the availability of the ACA Medicaid coverage raises the opportunity cost of crime. This prediction is particularly relevant for the ACA expansion since it primarily affects childless adults, a population likely to contain individuals who engage in criminal behavior. We validate this forecast empirically using a difference-in-differences framework, estimating the expansion's effects on panel datasets of state- and county-level crime rates. Our estimates suggest that the ACA Medicaid expansion was negatively associated with burglary, vehicle theft, homicide, robbery, and assault. These crime-reduction spillover effects represent an important offset to the government's cost burden for the ACA Medicaid expansion.


    Does Regulation of Physicians Reduce Health Care Spending?
    ABSTRACT: The medical community argues that physician fear of legal liability increases health care spending. Theoretically, though, the effect could be positive or negative, and empirical evidence has supported both cases. Previous studies, however, have ignored the fact that physicians face risk from industry oversight groups like state-level medical licensing boards in addition to civil litigation risk. This paper addresses this omission by incorporating previously unused data on punishments by oversight groups against physicians, known as adverse actions, along with malpractice payments data to study state-level health care spending. My analysis suggests that, contrary to conventional wisdom, spending does not rise in response to increased risk. An increase in adverse actions of 16 (the year-to-year average) is associated with statistically significant, annual decreases in state spending on hospital care of approximately $22 million, and on prescription drugs of nearly $10 million. Malpractice payments are estimated to have smaller, statistically insignificant effects.


    Does employer-provided health insurance constrain labor supply adjustments to health shocks? New evidence on women diagnosed with breast cancer
    ABSTRACT: Employment-contingent health insurance may create incentives for ill workers to remain employed at a sufficient level (usually full-time) to maintain access to health insurance coverage. We study employed married women, comparing the labor supply responses to new breast cancer diagnoses of women dependent on their own employment for health insurance with the responses of women who are less dependent on their own employment for health insurance, because of actual or potential access to health insurance through their spouse’s employer. We find evidence that women who depend on their own job for health insurance reduce their labor supply by less after a diagnosis of breast cancer. In the estimates that best control for unobservables associated with health insurance status, the hours reduction for women who continue to work is 8 to 11 percent smaller. Women’s subjective responses to questions about working more to maintain health insurance are consistent with the conclusions from observed behavior.


    Just For Fun


    Economics Conference Bingo

    ABSTRACT: We describe a bingo-style game intended to be played at economics conferences. Early results from implementation of the game by economists at conferences suggest that fun increases more than a full standard deviation. Further study of the effects of the game is ongoing.
